Abstract
Abstract A digital imaging system uses an analog/multi-level memory to store image data. The stored analog/multi-level data can then be accessed directly by an analog device or the data can be accessed by an A/D converter for conversion to a digital format. The digital data is then routed to any number of desired digital devices. By using an analog/multi-level memory instead of a digital memory to store image data, problems associated with storing large amounts of digital data are minimized or eliminated, such as loss of information from image compression and high costs of large digital memories and signal processing and compression circuits.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
91 words
A method of operating an imaging system, comprising: providing analog image data having a bandwidth from an image sensor; determining a number of non-volatile memory sections into which the image data will be written based on said bandwidth; and writing the image data into said number of memory sections in a parallel pipelined manner, wherein said bandwidth requires sampling at a first frequency and said writing involves sampling and writing at a second frequency, and wherein said determining a number is based on relation of the first and the second frequencies.
